Libvirt 库是一种实现 Linux 虚拟化功能的 Linux® API,它支持各种虚拟机监控程序,包括 Xen 和 KVM,以及 QEMU  和用于其他操作系统的一些虚拟产品。

libvirt 提供一种虚拟机监控程序不可知的 API 来安全管理运行于主机上的来宾操作系统。libvirt 本身 不是一种工具,                 它是一种可以建立工具来管理来宾操作系统的 API。libvirt   本身构建于一种抽象的概念之上。它为受支持的虚拟机监控程序实现的常用功能提供通用的 API。libvirt 起初是专门为 Xen 设计的一种管理 API,后来被扩展为可支持多个虚拟机监控程序。

现代 Linux 发行版的包管理系统处理这点依赖不成问题。
